In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative measure of lens speed; increasing the f-number is referred to as stopping down. The f-number … Il rapporto focale, o f-stop, indicato con il simbolo ƒ (o f), indica il rapporto esistente tra lunghezza focale (F) di un obiettivo ed il diametro (D) del diaframma in cui entra la luce. Generalmente viene chiamato anche più semplicemente "diaframma" nella terminologia fotografica. Questo rapporto, espresso graficamente con ƒ/ o f/ seguito da un numero, det… Webelectronically.

The higher the f-number of a given lens the smaller the aperture will be, restricting the amount of light that will pass through.
